I spent a month using Claude to roll back the last 7 years of UI changes on 170+ sites

A developer created a Chrome extension to revert website UI changes, aiming to restore more functional designs from the past seven years across over 170 sites. Initially, methods like fetching styles from the Wayback Machine or using an algorithm to interpret frontend elements proved inefficient. To overcome loading issues and interpretation problems, the developer utilized opus 5.5 over a month to find past screenshots and individually implement designs for high-traffic pages, iteratively testing against 2019 captures to resolve aesthetic and functional issues.

This account details a novel approach using Claude 5.5 to restore older website UIs, unlike previous attempts that relied on the Wayback Machine or algorithmic interpretations.
